Description

[Detailed Description of the Invention] (7) Summary A new passenger trolley is connected between the power vehicle and the loading truck of a single-rail transport vehicle. The passenger trolley is equipped with a seat on which a person can sit, and is further equipped with a handbrake. The seat is
It is rotatably suspended from a support on the side of the passenger vehicle. The seat is further supported from below by arcuate guide rails and guide rollers. The inclination of the seat can be adjusted in the direction of gravity, and this positional relationship can be fixed and further adjusted repeatedly.

The seat is stable because it is supported from the upper side and the bottom. There are pillars on the sides to give the occupants a sense of security.

(b) Technical field Single-gauge transport vehicles are installed in hilly areas such as mandarin orange orchards and are used to transport agricultural products, fertilizers, etc. There is only one rail, so it is easy to install. It has a drive mechanism that meshes with the rack and pinion, so it can easily go up or down steep slopes.

A single-rail transport vehicle is made up of a power vehicle and a truck connected together. A power vehicle includes a power transmission system such as an engine, a reduction gear, and a pinion, and a braking system. Braking systems often include a normal stop brake, a constant speed brake, and an emergency stop brake.

A normal stop brake applies the brakes when the brake rod collides with a hit rod placed on the side of the rail. The brake lever is sometimes moved by hand.

The trolley only has a running function and has no power or braking mechanism. All luggage will be transported on trolleys.

Single-track transport vehicles are not allowed to be ridden by humans. This is because it is dangerous. Also, there is no space created for people to ride.

Since there are no humans on board, the powered vehicles run unmanned from the beginning to the end of the laid rails.

At the starting point, one worker loads or unloads the load, unlocks the stop brake, and pulls hard on the engine starting wire to start the engine and start the motor vehicle.

The transport vehicle runs unmanned on rails. At the end point (the point where the train should stop), a brake rod is placed on the ground near the rail. When the single-rail transport vehicle reaches this point, the brake rod collides with the brake rod, causing the brake rod to rotate. This activates the brakes. The transport vehicle stops.

The other worker at the end of the line unloads or loads the load, switches gears in the opposite direction, and starts the engine again.

In this way, single-gauge transport vehicles generally run unmanned.

However, one worker must be on standby at each end of the rail. The number of people engaged in agricultural work is decreasing, and it is difficult to always have two people working on a single-track transport vehicle.

Therefore, the following method is used as an expedient.

One person does all the work. A single-gauge transport vehicle is started at the starting point, then walked together with the transport vehicle to the terminal point, where loading and unloading work is done. In other words, -% one person is always moving along with the single-rail transport vehicle.

The law stipulates that no humans are allowed to ride in single-gauge transport vehicles. However, since single-track vehicles run faster than walking speed, it is difficult to follow them. Moreover, there are many slopes, making it difficult to walk in some places.

Therefore, in reality, workers often travel on single-track transport vehicles rather than on foot.

Single-track transport vehicles were not originally designed to be ridden by humans, so they are often dangerous. You may fall and get injured. It's not necessarily safe because you're riding in a small space on the cargo platform.

The Ministry of Agriculture, Forestry and Fisheries also reportedly intends to permit passenger mole rail.

In fact, there are many people who ride single-gauge transport vehicles, and they cannot do agricultural work without riding, so it is unrealistic to ban them from riding. It is said that it is prohibited to ride on a bicycle because it is dangerous, but on the contrary, it would be better to create something that is technologically perfect so that it can be ridden safely.

Since people still ride them today, they should make something that they can ride with peace of mind.

For this reason, the Ministry of Agriculture, Forestry and Fisheries also seems to be planning to ease restrictions.

1) Prior art and its problems Since it was forbidden for people to ride on single-rail transport vehicles, there are no single-rail transport vehicles that are widely known or used by the public. For this reason, there is little technical accumulation.

Although it is just an idea,
No. (released on February 19, 1977), Japanese Patent Publication No. 1983-222
No. 18 (released on February 19, 2019) connects a seated car for people to ride between the power car of a single-gauge transport vehicle and a trolley (baggage car).

In the former, the seat car and trolley are separate. The latter had a new seat built at the front of the trolley.

Both have two independent brake systems. Even if one brake fails, the other brake can stop the vehicle, which prevents the vehicle from running out of control on steep slopes. In fact, when it comes to single-track transport vehicles running on steep slopes,
Measures to prevent runaway behavior are extremely important.

Single track transport vehicles are used on sloped areas. It often reaches an angle of inclination of 80° to the horizon, and sometimes even as much as 45°.

The seats of these known passenger cars are fixed.

The passenger car tilts according to the slope of the rail. The inclination of the seat also follows the inclination of the rail.

However, it is desirable for humans to always support their upper bodies along a vertical line, regardless of the direction of travel.

Even if the rail is sloped downward or upward,
It is desirable that the seat not follow the inclination of the rail, but always remain approximately horizontal.

2) Technical issues A passenger single-rail transport vehicle for carrying people is required to:

(1) The vehicle can be stopped and started by the driver's operation.

Even if it goes out of control, it can be stopped.

(2) The passenger trolley on which the driver rides must be equipped with an independent brake, separate from the braking device of the motor vehicle.

(3) When applying the brakes, ensure that the driver does not get injured due to sudden braking.

(4) The driver should be able to maintain a comfortable posture when going up and down slopes, mountains, and valleys.

Problems (1) and (2) can be solved by providing a new brake to the passenger trolley. (3) can be overcome by selecting and adjusting the brake.

Issue (4) seems to have gone unnoticed until now. However, the inventor believes that this is also an important issue.

If the relationship between the seat and the wheels of a passenger trolley is fixed, the user is likely to slide forward from the seat due to gravity, especially when going downhill. When going uphill, your center of gravity will shift to the rear, making you feel like you're going to flip backwards.

The passenger carriage of a single-gauge transport vehicle travels on a track with many ups and downs, like a roller coaster.

However, unlike a roller coaster, the length of the vehicle is not large. Passenger trolleys are short in the front-rear direction, but rather large in the vertical direction. Because it is vertically long and unstable, there is a high possibility of it falling, especially forward or backward.

It is preferable for the seat to be horizontal, not only from a physical safety standpoint, but also psychologically.

In this way, problem (4) is an important requirement to be overcome.

(k) Structure of the present invention The inventor of the present invention came up with the idea that the seat should be able to swing around a fulcrum like a swing and be fixed at any position. Two pillars are provided on both sides of the passenger trolley facing upward from the frame, and the seats are suspended on the pillars. In this way, the seat can swing back and forth about the fulcrum, and the occupant's posture can always be moved in a comfortable direction. There are also pillars on the left and right sides, which gives you a sense of security.

However, since it is suspended from pillars, the pillars tend to bend under the weight. Therefore, the vehicle frame and supports must be made extremely strong.

If the strut stands upright from the vehicle frame, there will be no problem with deflection, but in order to prevent the strut from getting in the way, the strut is shaped like an R, bending from the rear to the front. Therefore, the bending moment generated at the bent portion of the strut becomes extremely large at the connection point between the vehicle frame and the strut. The pillars must be thick and heavy to prevent bending and buckling.

Therefore, a combination of a guide rail and a guide roller is provided on the bottom surface. The guide rail has an arc shape centered on the fulcrum.The guide rollers sandwich the top and bottom of the guide rail (4 wheels).
Either, or it is held in place by having two guide rails (top and bottom) (two wheels). The guide rail and guide roller are each fixed to either the vehicle frame or the seat.

The load of the seat is distributed and applied to the vehicle frame by the support columns, guide rails, and guide rollers.

If left as is, the seat would simply swing around the fulcrum, so a rack along an arc was provided below the seat, and the fixed claws engaged with the rack.

When you step on the seat adjustment pedal, the fixing claw will detach from the rack.
Seats are free. When the seat adjustment pedal is released, the fixing pawl engages the rack again and the seat is fixed.

The bogie of the single-rail transport vehicle of the present invention includes (1) upper wheels and a lower axle that sandwich the rails from above and below, and (2)
) a vehicle frame that supports the upper and lower axles on rotary mills; (3)
(11) (4) A seat that is rotatably suspended from the pillar by a bottle; (5) A seat that is formed in an arc shape with the bottle as the center and that extends upwardly from the car frame. (6) a guide rail that is fixed to the seat; and (6) a guide roller that is structured so that it can roll on the guide rail and does not come off the guide rail and is connected to the vehicle frame or the seat that is not fixed to the guide rail. , (7) a rack arranged in an arc shape with the bin as the center and installed at the bottom of the seat; (8) a fixed claw that can be engaged with or disengaged from the rack provided on the vehicle frame; and (9) a fixed claw that can be engaged with or disengaged from the rack. (10) A pinion fixed to the lower axle of the vehicle chassis and meshing with the rack; (11) An emergency brake comprising an emergency brake drum provided coaxially with the pinion or via a deceleration/acceleration mechanism. (12) Installed on the seat (1) to activate the emergency brake.
2) Consists of a hand brake.

By operating the stop/start lever 14, the stop brake 16 is activated or released.

A constant speed brake 15 provided on the side of the vehicle body 7 prevents the vehicle from driving out of control due to excessive speed when exiting the vehicle. The stop brake 16 can stop the power transmission mechanism connected to the pinion 18 in conjunction with the stop/start lever 14 .

The emergency stop brake 17 is activated in the event of an abnormality in which the vehicle speeds up too much when exiting the vehicle, and automatically stops the power vehicle.

In this way, the motor vehicle 1 includes a power mechanism and a braking mechanism. The braking mechanism includes a stop brake, an emergency stop brake,
It consists of three constant speed brakes.

Such a motor vehicle has been manufactured by the present inventor for some time.

The cart 3 is used to carry luggage. The power vehicle 1, the passenger truck 2, and the truck 3 are connected by connecting rods 19, 19.

The truck 3 has a wide loading platform 20 supported by one or two racks 21.

The vehicle frame 21 has two upper wheels 22 and two lower axles 23 attached to a frame made of aluminum alloy, cast iron, or the like via the axles. The vehicle rack 21 is connected to the loading platform 20 so that it can be turned left, right, up and down. Even if the rail 4 curves vertically or horizontally, the carriage 21 can turn around and follow the curvature of the rail. Luggage shelves 24 and 24 are erected in front and behind the cart 3. . Fences can be erected on the sides if necessary.

FIG. 3 is a rear view of the passenger trolley 2, and FIG. 4 is an enlarged side view.

The passenger trolley 2 is supported by a carriage 25 with respect to the rails 4. The vehicle frame 25 is made of aluminum, aluminum alloy, cast iron, or the like.

An upper wheel 26 and a lower axle 27 that sandwich the rail 4 from above and below are rotatably provided on the vehicle frame 25 via the axle (15). One of the lower axles is provided with an emergency brake 28 and a pinion 29 connected to it and meshing with the rack 5. When the emergency brake 28 is activated, the pinion 29 is stopped and the passenger trolley 2 is stopped.

Above the vehicle frame 25, a bottom plate 30' and pillars 30, 30 integrally formed on the sides thereof are provided. There are pins 31 and 31 on the upper left and right sides of the support column, and the seat 32 is suspended from the pins 31 so as to be able to swing freely. Seat 32 also has a backrest.
There is also a horizontal board. The seat is also supported from the bottom. pin 31
An arcuate guide rail 44 centered at is fixed directly above the vehicle frame 25. At the bottom of the seat 32, four guide rollers 45 are provided that roll on the front and rear of the guide rail 44, and the top and bottom of the guide rail 44. The seat 32 rotates around the pin 31 by the combination of the guide rollers 45 and the guide rails 44. The load applied to the seat is distributed to the support columns and guide rails, and then transmitted to the vehicle frame. A hand brake lever 33 of a single-lift type is provided below the side of the seat 32. From the handbrake lever 33 to the handbrake wire cable 34
extends and is connected to the emergency brake 28.

A ratchet 35 is fixedly installed around the fulcrum of the handbrake lever 33. When the handbrake lever 33 is pulled up, it is fixed in that position by the ratchet 35. When the lever button 33' is pressed, the handbrake lever 33 is released from the ratchet and can be returned to its original position. A limit switch 3 is provided adjacent to the handbrake lever 33. When lever 33 is pulled up, limit switch 36 is actuated by the lever. switch 3
The on/off signal of 6 is transmitted through an engine stop cord 37 to stop the engine 11 of the power vehicle 1. After the engine stops, the emergency brake 28 starts working and the pinion 2
9 stops and a braking force is generated on the passenger trolley 2. In this way, the entire transport vehicle is stopped. The seat 32 can swing back and forth around the pin 31. The height of the seat board, the backrest, etc. are set so that the center of gravity of a person sitting on the seat 32 is directly below the pin 31. Since it is dangerous for the seat to constantly swing, a separate fixing mechanism is provided.

A seat adjustment pedal 39 is provided 1, and an arc-shaped rack 41 is fixed to the front lower part of the passenger trolley 2.

A fixed claw 42 that can be raised and lowered is provided below the rack 41. The fixed claw 42 and the seat adjustment pedal 39 are connected by a seat adjustment wire cable 40.

When the seat adjustment pedal 39 is not depressed, the fixed pawl 42 is raised and engaged with the rack 41. seat 32
The angle of inclination with respect to the vehicle frame 25 and the support column 30 is fixed.

When the seat adjustment pedal 39 is stepped on, the fixed pawl 42 is lowered and the rack 41 is released. The seat 32 swings freely relative to the column 30. Since the center of gravity, including the human body, is set to be directly below the pin 31, if the occupant's posture is correct, the seat 32 will move due to gravity, and the human's upper body will be in a position facing the same vertical direction as before. Changes to At this point, release the pedal 39. The fixed claw 42 engages with the rack 41. In this position the seat 32 is fixed again.

The seat inclination angle can be adjusted frequently according to the vertical movement of the rail.

(G) Structure of the vehicle frame The structure of the vehicle frame of the passenger trolley 2 will be explained with reference to FIG. This is similar to the structure of a vehicle frame such as a truck or a power vehicle.
It consists of an upper wheel and a lower axle, with a rail sandwiched between them.

In the case of a cart, the rails are held between two upper wheels and two lower axles. The axle is fixed, and bearings are installed between the axle and the wheel.

In the case of a powered vehicle, there are two upper and two lower wheels, and one of the lower axles serves as the drive shaft. A drive pinion is fixed to this axle, and a lower axle, which is an idler, is attached via a bearing.

In this respect, the chassis of a passenger trolley is the same as the chassis of a power vehicle. A binion is fixed to one of the lower axles. This is not for driving, but for braking.

The vehicle frame 25 has a lower axle 51 passed above both sides of the frame 50, and is fixed at both ends with poles 52 and 53. An upper wheel 26 (19) is attached to the middle of the lower axle 51 via a bearing 54.

Positioning is done by a collar fitted onto the axle.

The front axle of the lower axle does not appear in this diagram.

This is a shaft that is cantilever-supported by the frame, and a lower axle is provided via a bearing. The reason why the lower axle is supported in a cantilever manner is because the support column 6 that supports the rail 4 is connected to the rail by a coupling fitting, and the sides of the rail must be open.

The rear wheel 60 of the lower axle is driven by bearings 61,62.
It is rotatably supported by the frame 50.

The lower axle 27 has a bearing 6 at the end of the lower axle 60 on the rail side.
3 and is removed and screwed in by a bolt 64.

An emergency brake drum 65 is attached to the outer end of the lower axle 60.
is inserted through a key and fixed with a washer 6 and a bolt 67.

An emergency flake shoe 68 is opposed to the inner circumferential surface of the emergency brake drum 65 with a slight gap therebetween (20).

When the occupant pulls the handbrake lever 33, the tensile force is transmitted by the wire cable 34, causing the emergency brake shoe 68 to expand in diameter. The emergency brake shoe 68 contacts the inner peripheral surface of the brake drum 65, and the brake drum 65
to stop.

Binion 29 and emergency brake drum 65 are connected to lower axle 60
Since the brake drum 65 was rotating integrally through the brake drum 65, when the brake drum 65 stopped, the pinion 29 also stopped. Since the binion 29 is engaged with the rack 5 on the side of the rail 4, the passenger trolley 2 is stopped.

In this example, the binion 29 and the emergency brake drum 65 are coaxially connected. , h:, Shikashi C. It is sufficient that both of them are connected to each other, and there is no problem even if a deceleration or speed increase mechanism is interposed between them.

Although a dual-off user brake is used as the emergency brake 28 in this example, other brakes may be used.

(b) Effects According to the present invention: 1. (1) In the past, it was often dangerous for people to be forced to ride on single-gauge transport vehicles that had little room for people to ride. According to this invention, since a passenger trolley is connected to a single-gauge transport vehicle, agricultural work can be carried out safely and efficiently.

There are seats, so there is less fatigue.

(2) Since the passenger trolley is also equipped with a brake, the passenger can easily stop the vehicle. If the truck 3 is also provided with an emergency brake 69, safety will be further improved.

(3) The seat's longitudinal inclination is adjusted according to the inclination of the rails, so that the human's upper body is always maintained at or close to vertical, providing a comfortable ride.

(4) Finally, consider the ease of movement of the swing type (suspended from a support) and the guide roller type.

The center of gravity G is below the center point 0. Suppose that because the rail is tilted by θ, the direction of gravity W acting on the center of gravity G is tilted by θ.

FIG. 6 is a diagram for explaining the mechanics of a swing type.

If the distance between the center (fulcrum bin) 0 and the center of gravity G is l, the normal force N acting on the 0 point is N = Wcosθ (1) The rotational moment M acting on the 0 point is M = 1Wsinθ (2) At the fulcrum, N acts as friction and M acts as a force to rotate the seat relative to the fulcrum bin.

Since the ease of movement U can be defined by M/N, U =
It is given by 1-〇 (8). If the distance 0G=l is large, in the case of a trapeze type, it can rotate easily and always follow the direction of gravity.

FIG. 7 is a schematic diagram showing the mechanics of the guide rail and guide roller type. Center point 0 (this is a point in space, not an actual object) and guide rail xY
Let the distance be L. Guide (23) Assume that there are guide rollers at two points A and B on the rail. The angle looking at the two points A and B from the center point 01 center of gravity G is 2α,
Let it be 2β.

Suppose that the direction of gravity is tilted by θ.

According to the law of sine, the forces Pa and Pb acting on the rollers A and B in the directions of the GA and CB forces are as follows.

The normal force Na perpendicular to the rail acting on roller A,
The horizontal force Sa parallel to the rail is expressed by the angle between OA and AG (
Since it is β-α), the Na-Pa part (β-α) (6) Sa= Pa5in (β-α) (7).

(24) Vertical force Nb1 horizontal force Sb acting on roller B is Nb-P
bcOs(β-(t)(8)Sa=-Pb5in
(β−α)(9). There is an exchange of horizontal force between rollers AB, but since this is an internal force, it disappears when considered as a whole.

Overall, the ratio of vertical force to horizontal force is jan (β
−α)−θcotβ (1o). This is,
It shows the ratio between the force that rotates the roller and the frictional force that attempts to stop the roller.

If the effective radius of the roller is r, the ease of movement V is: V = r tan (β-α)tanθcObβ (
11).

Equations (3) and (11) express the ease of movement of the swing type and guide roller type. Naturally, this is proportional to the sine of the tilt angle θ. These coefficients are the problem.

Taking the ratio of equations (3) and (■), and assuming that α and β are sufficiently smaller than 1, the ratio of ease of movement is given by: Depending on the values of r and L, this may be about ten times. It turns out that the swing style is much easier to move.

Since the present invention uses both the swing type and the guide rail type, the ease of movement of the seat is smoother than when only the guide rail is used.
